My particular use-case (and I feel others are in this boat) is that I play in-person. As the GM, I load my game on my computer, then login with a player account in another browser and cast that to my TV. My players sit around the couch, with their character sheets from another website on their laptops or mobile devices and roll real dice. It would be better if Roll20 were an actual one-stop shop for us by making character builder a completely separate function that doesn't require the user/player to launch the game itself.
